A vent of foldable tent frame

ABSTRACT

The present invention provides a foldable tent frame with a double-roof vent typically comprised of poles, stay bars and roof cross braces hinged on a tip hub, all of them construct the main body of the tent, a small ventilation roof-boom frame connected on the top center of the main body of the tent; said ventilation roof-boom frame is consisted of a central stem, side struts, upper bracing ribs and central rib-hub; said central stem is fastened on the up side of the tip hub with the low end vertically, and fastened on the bottom side of the rib-hub with the top end; each side strut is hinged on one side of the corresponded roof brace with the low end, and hinged on the same side of the coordinated upper bracing rib with the top end; all the upper bracing ribs are hinged on the central rib-hub with the tip ends respectively. This structure can make the whole tent mount and disassemble conveniently and rapidly, and guarantee the tent use normally.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a tent, and more particularly to adouble-roof vent of foldable tent frame.

2. Description of Prior Art

In accordance with the conventional technology, the foldable tent framewith top vent is typically comprised of poles, stay bars and roof crossbraces hinged on a tip hub, all of them construct the main body of thetent, a small ventilation roof boom frame plugged on the top center ofthe main body of the tent, coordinating to it the awning of the tenthaving a ventilation hole built upon the central portion, and a topshield built upon the ventilation hole for covering on the ventilationroof-boom frame by tying connection with ropes, so that said ventilationroof-boom frame can pass through the ventilation hole to be coveredexactly by the top shield as putting on the awning over the tent frameto form a double-roof vent at the top center of the tent to get goodventilation effect, therefore the tent with the double-roof vent iswelcome by the customers.

But, said ventilation roof-boom frame is designed to in separated partfrom the main body of the tent, so in assembling, firstly need to pitchup the whole tent frame, then mount the roof-boom frame on the topcenter, so that the operations of pitching and collapsing the tentbecome more complicated, especially to the bigger size and higher tent,mounting and disassembling the roof-boom frame is more inconvenient. Andthe individual roof-boom frame and the main body of the tent are easy tobe lost as in disassembling and storing, so that it affects to thenormal use.

OBJECTS AND SUMMARY OF THE INVENTION

It is therefore a main object of the present invention to provide afoldable tent frame with a double-roof vent that can be efficientlypitched up or folded to a compact configuration conveniently andrapidly, and guaranteed to be used normally.

For achieving the above-mentioned object, the present invention providesa foldable tent frame with a double-roof vent, which is typicallycomprised of poles, stay bars and roof cross braces hinged on a tip hub,all of them construct the main body of the tent, a small ventilationroof-boom frame connected on the top center of the main body of thetent; said ventilation roof-boom frame is consisted of a central stem,side struts, upper bracing ribs and central rib-hub; said central stemis fastened on the up side of the tip hub with the low end vertically,and fastened on the bottom side of the rib-hub with the top end; eachside strut is hinged on one side of the corresponded roof brace with thelow end, and hinged on the same side of the coordinated upper bracingrib with the top end; all the upper bracing ribs are hinged on thecentral rib-hub with the tip ends respectively.

The foldable tent frame with a double-roof vent is typically comprisedof poles, stay bars and roof cross braces hinged on a tip hub, all ofthem construct the main body of the tent, a small ventilation roof-boomframe connected on the top center of the main body of the tent; saidventilation roof-boom frame is consisted of a central stem, side struts,upper bracing ribs and central rib-hub; said central stem is fastened onthe up side of the tip hub with the low end vertically, and fastened onthe bottom side of the rib-hub with the top end; each side strut ishinged on one side of the corresponded roof brace with the low end via apivot bearing, and hinged on the same side of the coordinated upperbracing rib with the top end; all the upper bracing ribs are hinged onthe central rib-hub with the top ends eccentrically and respectively sothat the upper bracing ribs are closed between the roof cross braces andthe side struts in folded state for folding to a minimalist volume.

As utilizing above-mentioned project, due to the ventilation roof-boomframe is integrated into the main body of the tent frame as a whole one,the ventilation roof-boom frame is pitched up or folded up along withthe main frame of the tent without individually mounting ordisassembling it, hence the tent applying the present invention can beefficiently pitched up or folded to a compact configuration convenientlyand rapidly; and avoids losing the separated part, and guaranteed to beused normally.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIG. 1 to FIG. 3, a foldable tent frame with a double-roofvent provided by the present invention is typically comprised of poles1, stay bars 2 and roof cross braces 3 hinged on a tip hub 4, all ofthem construct the main body of the tent, a small ventilation roof-boomframe connected on the top center of the main body of the tent.

Said ventilation roof-boom frame is consisted of a central stem 5, sidestruts 6, upper bracing ribs 7 and central rib-hub 8, wherein saidcentral stem 5 is fastened on the up side of the tip hub 4 with the lowend vertically, and fastened on the bottom side of the rib-hub 8 withthe top end; each side strut 6 is hinged on one side of the correspondedroof brace 3 with the low end, and hinged on the same side of thecoordinated upper bracing rib 7 with the top end; all the upper bracingribs 7 are hinged on the central rib-hub 8 with the top endsrespectively. Therein, for avoiding each member bar interferes in foldedstate and folding to as smallest as possible in volume, said each sidestrut 6 is hinged on one side of the corresponded roof brace 3 with thelow end via a pivot bearing 9, and hinged on the same side of thecoordinated upper bracing rib 7 with the top end; all the upper bracingribs 7 are hinged on the central rib-hub 8 with the top endseccentrically and respectively so that the upper bracing ribs 7 areclosed between the roof cross braces 3 and the side struts 6 in foldedstate for folding to a minimalist volume.

As tending to fold the tent frame, just need to follow the way offolding the conventional tent frame to fold the present invention, suchlike in the state shown in FIG. 1, close the poles 1 of the main body tobring the stay bars 2 and the roof cross braces 3 to close, cooperatingto FIG. 4 and FIG. 5, meanwhile the side struts 6 will draw the upperbracing ribs 7 under the driving coming from the roof cross braces 3 toclose together until the ventilation roof-boom frame is completelyfolded along with the main body folding to finish folding the wholetent, as shown in FIG. 6.

As tending to pitch up the tent frame, also need to follow the way ofpitching the conventional tent frame to pitch the present invention,such like in the state shown in FIG. 6, draw out each pole 1 to bringthe stay bars 2 and the roof cross braces 3 to spread out, cooperatingto FIG. 4 and FIG. 5, meanwhile under the drive of the roof cross braces3, the side struts 6 will push up the upper bracing ribs 7 until theventilation roof-boom frame is completely extended out along with themain body stretching to finish pitching the whole tent, as shown in FIG.1.
